Breathing Underwater Is Not A Problem With This Unique Swimming Pool

Argentinian artist Leandro Erlich created an interactive experience for visitors, allowing each guest to view his Swimming Pool installation both from underwater and above ground. Though it looks like a normal pool, it's actually an illusion created by placing a clear surface towards the upper part of the pool with a little bit of water on top. This gives the illusion of depth from above and water from below.
